4 1 Be it knownthat JoHNH; M mnnfa citi- Z611 of the United Statesiof America, resid- 7 ingat MacDunn, in the, county of Fayette .and State of WVest Virginia, has invented new and useful Improvements in Car-Con trolled Trolley-Line Cut-Outs, of which! the following is .aw specification. v

In 'mine tracks Where a branch" track. leaves the main track, ithe trolley wire suspended above the-latter must cross the main track to provide means for a mine car taking the branch track. 'This spanning section of the trolley Wire constitutesla hazard to the lives ofhum'ans and animals passing down the main track who must passbeneath this section of tr-olley'wire. It is a common practice to shield this irnsome manner or -other and ordinarily'bymeans of depend I invention to so construct the trolley Wire 'ing Wooden guards disposed on opposite for the branch track as to.- make that" see- Figure' 5 IS a detail leva-tional ot oneof the .IIn-olstRacceptable 'formsoficuta outsfbut-Tobviouslyanygsource of cutaout,

tion spanning the main track normally dead or inactivetenergizing it,/hoWever, from the main trolley WlI6 through an interposed w car controlled cut-out, so that as the train takes the branch track, the normally dead section is rendered active'or aliveforthe operation of the motorpropellingthe passing train.

In the construction illustrated, a specific j emb-odiment has been adhered to, butfto this the invention isjnot to be restricted -iurther than is prescribed mithe annexed claims.
